My skin has either really changed over the years, or I am just becoming more knowledgeable about skincare. I have oily/combination skin, depending on the season, and seborrheic dermatitis which also makes my skin more sensitive. It has been a battle finding the right combination of products to control the oil and blackheads, but not irritate my skin. This product definitely didn't help! According ...read moreto the directions, it is best used in the morning so I would add it to me moisturizer/sunscreen and it would just burn my skin. Stupid me, I didn't realize this was a "problem" until I started learning more about skin irritants; that is a whole other topic in itself! :) I just thought if it tingled or burned a smidge, it was "working." Uh, NO! If your skin is sensitive, I would opt for another product. However, if it is not, it may be worth it to add. I did notice SLIGHT brightening effect in the 6 short weeks I used it. I would say that a serum would be more convenient; this powder comes with a teeny spoon to retrieve the powder and it can be a big mess, resulting in lost product. However, it is convenient that you can pretty much mix it with any product. I am going to try KIMINSC's suggestion of using a crushed vitamin c pill and see if that is as bothersome. All in all, I would skip this product and try something else. — 1 year, 1 month ago

The first problem I had with this, is that it does not mix well with certain products. More importantly, I did not notice any appreciable difference in the appearance of my skin after using this daily for 6 months. I would not buy this again.
